    How do I get a transfer function in the form:

    1+ Tz
    k ---------
    1+ Tp

    from this circuit?


    Vin--R1---C1--------Vout
    ...................|
    ...................C2
    ...................|
    ...................R2
    ...................|
    ...................GND

    ignore dots just used them for spacing....
    I did a voltage divider to get the transfer function:
    [with s = jW]

    R1 + 1/sC1
    ------------------
    R1 + R2 + 1/sC1 + 1/sC2

    is there a trick to changing the form?

    What form do you want Tz and Tp to be in? Consider what the units will be.
